The general rule for rotation of an object 90 degrees is (x, y) --------> (-y, x). You can use this rule to rotate a pre-image by taking the points of each vertex, translating them according to the rule, and drawing the image
The expression can be simplified as:
k^3(k7/5)^-5
= k^(3+-5) * (7/5)^-5
(Collecting the powers of k at one side and the constants at other side)
= k^-2 * (5/7)^5
(Solving thr integer powers)
= k^-2 * (3125/16807)
The best method i found is guess-and-check. Just guess the three numbers. If you do this you should get 6+8+10.
The interior angles of a pentagon all add up to be 540°
Answer:
x = 7
y = 5
Step-by-step explanation:
6x - 2y = 32
4x - 2y = 18
2x = 14
4x - 2y=18
x = 7
4 * 7 - 2y = 18
x = 7
28 - 2y = 18
x = 7
2y = 10
x = 7
y = 5
there is only 1 solution for this equation is (7;5)
Done :))
